sipX version 3.10 released

A bit late but I was busy doing some work on mt OCS installation. For this Friday there is a customer demo planned with MS Exchange 2007, OCS 2007 connected to a HiPath 3800 via a sipX gateway and the ESTOS Call Control Gateway.

At least I finally got it kind of installed and just found that there is a new sipX release. The major changes are as below:

  • New and improved look & feel (skin) and new project logo
  • Automatic device discovery
  • Personal auto-attendant for every user on the sytem
  • Integration with Microsoft Active Directory and Exchange 2007
  • Schedule based find-me / follow-me functionality for every individual user, user self-configurable
  • Enhancements and extensions to the Call Center ACD server
  • New plug & play devices: Additional Polycom phones and new firmware, Linksys, IpDialog, Nortel video phone
  • Updated support for plug & play management of Polycom, LG-Nortel, Audiocodes, and Snom phones

TCP / UDP traffic router sipX

Last week I spend about 10 hours installing my unified-communications.local domain. It is a Windows 2003 Server Domain containing five servers: Domain Controller with Sub C, Exchange 2007 Server, OCS 2007 Standard Server, OCS 2007 Edge Server and an OCS 2007 Mediation Server.

I tried to network the Microsoft UC applications to our HiPath Open Communications platforms directly but we still have the same issue as in the past with Beta 2 of Exchange 2007. Microsoft expects our signalling and payload in TCP instead of UDP. Siemens HiPath operates according the SIP standard on UDP RFC 3261. So I was looking for a way besides the eicon Call Control software and a hardware based QSIG – SIP router.

And I found it in the open source application sipX

It is a fully blown SIP PBX that operates on both UDP and TCP and can be configured as middle ware application. One leg connected to the HiPath STMI2 card and the other to the Exchange 2007 UM role / OCS 2007 server.

Currently I have some postgreSQL issues with my box but as soon I get them resolved you can expect a complete step by step guide on setting this up.


New Software and a nice URL

After a few month absence from my private life I am back and there is whole bunch of new software versions out on the market!

VirtualBox Closed Source 1.5.4

Fine new features like RDP, USB and also USB over RDP are available using the closed source version.

Asterisk 1.6.0

Lots of new stuff like new dial plan, voicemail features and a really interesting enhancement on STUN

Also a special announcement for a new button on the SEN wiki homepage:

Next to inormation about Siemens Products and their partners can now third party vendors upload their own free apps. This is a massive improvement and a big step towards HiPath Open Communications! But I still miss the board 😉


New Asterisk Maintenace Release

The Asterisk development team proudly announced the releases of versions 1.2.20 and 1.4.6!

These maintenance releases were published just two weeks after the last ones. The development team fixed around 100 bugs on the free soft PBX.

These releases are available for download from They are distributed as both tar balls and patch sets against the previous releases. All release files have been signed with GPG keys from members of the Digium software development team to ensure authenticity.

The worrying bit is that Asterisk is talking about 100 big discovered bugs in just 2 weeks. Due to growing amount of users it is obvious that more bugs are found but the question I am asking can you securely use Asterisk in a business environment.
